(01109-257) The present invention has for'its object the cheap and rapid mechanical loading, elevation, or movement of spoil, shingle or other substances by an improved mechanism, the invention having for its underlying principle the use of centrifugal force for ejecting spoil inserted into suitably disposed rotor means for the loading, elevating or dumping of said spoil.

The invention maybe applied in many ways,

but without limiting the generality of the underlying principle hereinbefore stated, two constructional embodiments of the invention will be described, one, in the form of a light loader used either as part of the permanent equipment of a lorry or as a separate unit for filling alorry or other vehicle with spoil, shingle or other substances and the other as a permanent or readily collapsible loader having a mechanical screen and feeder means incorporated in the apparatus which extend the convenience and'use of same.

Briefly the invention may be said to consist'of a vertically disposed rotor into the side of the casing of which the spoil or other substance to be elevated or moved is fed by novel shaking and screening means, means being also provided for holding the, material within the rotor casing for a portion of the rotation of the rotor, while a gap is'also provided in the casing near the top through which the spoil is thrown, elongated chute means-being associated with the gap to guide the flying spoil to the desired point of disposal.

In describing the inventionrererence will be made to the accompanying drawings in which:-

Figure 1 shows an end elevation of the preferred form of apparatus which incorporates a mechanical screen and feeder.

Figure 5 shows an enlarged view ofthescreen and feeder driving mechanism.

Figure 6 shows a side elevation of the light loader type of apparatus for attachment to a lorry or for use as ,a separate unit.

Figure'l is-a partially sectioned side elevation thereof.

Figure 8 is-a sectional end elevation of Figure 7;

Figure 10 is an elevation of Figure 9 and Figure 11 is an enlarged sectional elevation of the driving pulley and shaft bearing means.

The preferred form of the invention as in Figures 1 to 5 will be first described, this form comprising a main frame I of suitable structuralv form having preferably two sides 2 and 3 mounted to base members 4 and 5 and an engine bed 6 on which an engine 1 or other suitable driving means is mounted.

Between the two sides 2 and 3, the rotor 8 and the chute 9 are mounted, the rotor 8 comprising (see Figure 4) two discs l0 and H with outwardly projecting peripheral flanges l2, the disc l0 being revolvably mounted by its central boss l3 on a rigid shaft It which is secured to frame side 2, the boss I3 having a pulley l5 mounted thereon, the disc H which is of ring form having a central admission hole It and being connected to the disc In only by two diametrally opposite, wear resisting material blades l'l preferably curved in the direction of rotation (as shown in Figure 3) To the rear l8 of the frame I (see Figure 3) two broad flanged pulleys l9 and 20 are revolvably mounted and to the front 2| of the frame I a similar pulley 22 is provided, this latter having tension adjustment means 23 of known type for applying tension to a broad belt 24 (preferably of rubber) which passes over the pulleys I9, 20 and 22 and contacts the periphery of the rotor 8 at the bottom and up one side thereof as shown in Figure 3.

The uppermost broad flanged pulley I9 \is provided with a drive pulley 25 or like to its shaft 26 (see Figure 4) to receive suitable drive such as by belt from the engine I.

The chute 9 is made up of preferably three detachable sections 21, 28 and 29, the bottom section 21 being supported by projecting under the engine bed 6 (see Figure 3) and having two stays 39 at opposite sides thereof which are fastened at their lower ends to frame sides 2 and 3 and have adjustment means 3! at the upper ends so as to enable adjustment or variation of the chute angle.

The middle section 28 is slightly broader at its lower end than the top of the bottom section 21 so as to leave a return opening 32, lugs 33 being provided to this section 28 for the removable attachment of a bottom 34 which extends not quite to the top of this section 28.

The top or end section 29 (see Figure 1) is open at the bottom havingonly a top and sides this section 29 being capable of independent raising or lowering by being held on to the middle section 28 by a rod 35 which passes down to an adjustment lever 36 (see Figure 2) pivotally secured to a plate3l on the top of middle section 28, this plate 31 having a series of adjustment holes 38 for engagement of the lever 36 in known manner, v v

With the chute 9" assembled, a continuous top 39 and sides 48 are presented to the spoil to confine it to a desired course, the shape of said chute. 9 being suited to conform with the natural tra- I jectory of spoil or substance'thrown by the rotor 8. a

To the outside of frameside ,3 the screen and feeder apparatus is mounted (see Figure 4) the screen 4! of desired mesh being mountedon two frames 42 which, in the vicinity of the frame side 3 are connected at their bottoms to two downward arms 43 of a shaker shaft 44 rotatably mounted on the frame side 3, a member 45 connecting the tops of the screen frames having a link 46 connecting it to a bracket 41 securedto frame side 3'. Y r I Above the screen there are sides 48 and a back 49 and from the latter a run back chute 59 passes to just below return'opening 32 of chute 9. 1

Below'the screen'4l suitable guide plates 5| direct the screened spoil to the feeder-52 which is inclined downwardly from itsouter'endl and projectsthrough the admission hole l6 of the rotor 8, the feeder' 52 at this end being carried by upward arms 53 on the shaker shaft 44, the outer end of thefeeder52 'being flexibly secured to the screen" 4! by'such means asspring steel supports 54. 7

The shaker shaft 44 is adapted to partially and sharply rotatein reverse directions so as to cause the screen 4| and feeder 52 to move reciprocally an in reverse directions, this motion of the. shaker shaft 44 being impartedrby an arm 55 (see Figure 5) secured to shaker shaft 44 which passes to a ball socketed connecting rod 55 which is corinected'to a ball type crankpin 57 adjustablysecure'd to a pulley 58 suitably rotatably mounted to frame 2 (see Figure 1) and adapted to receive a belt drive from the rotor pulley l5;

Nowreferring 'tothe light type of loader as in Figures 6 to 11, this type also has the rotor 8 and chute 9, but instead of having'the belt 24 covering portion of theperiphery so as to leave a gap from which the material is thrown from the rotor 8, a drum 59 encloses the rotor 8 and the chute 9 is secured toythe drum 59 in the'vicinity of a peripheral gap 69 therein.

This drum 59 comprises (see Figure 8) a short" I like, the cylindrical ring 6! not being continuous but having the peripheral gap .68 adapted to .coincide with chute 9. p H I. f

y The ends 55 of the cylindrical ring 6| between which gap 6D islocated (see Figure 7) project outwardly to, enable-bolt means 66 to secure a hard wear resisting liner 61 which coversthe inner face of the'cylindrical ring BI.

Thechute 9 issecured to the drum 59 by bolts passing through slotted holes 68 in said chute sides 40 so as to permit of peripheral adjustment movements of the chute 9 in relation to the drum 59 the chute 9 being secured tothe drum over the gap 60. V

The chute 9 may be constructed in three sec- 5 tions as in Figure 1 or as a single member as in Figure 6 and in the latter case the top 39 would not be continuous butwould terminate at the commencement of a tongue, 69 adapted to give deflection control, this tongue 69 which is free at 10 its outer end being adapted to beadjustably depressed by the operationof lever means 18 having notched'quadrant engaging means H.

In. this case, the engine bed 6 is provided on top of the chute 9 'for the'mounting thereto of. 15

the engine "1 and pivot means 12 are provided secured to the chute sides 40.

The lower edge of the gap 69 has a deflecting plate 13 secured therto projecting into the chute 9 and handle means 14 (Figure 6) may be secured to the 59'. f

Within drum 59 thereis rotor 8 comprising discs 10 and H as in Figure}! but no peripheral flanges l2, there being preferably four blades" I1; between discs I and II adjustably mounted on 25 brac'ketsl5 which are secured to's'a'id discs I!) andl. The rotor 8 has. a boss I3 (see Figure 11) to its disc l8 said bossl3 in this case being keyed to driving shaft I5, this latter passing through a bearing housing Tl secured'to dished end62 b al'l races or other suitable bearing means 18 being located within housing I 1; s The driving shaft 'lfi'at its outer end has pun ley means 19 secured thereto, preferably 'of the type shown in Figure 11. i

' Belt means 88connect the pulley 19;to the engine'!. V W The complete apparatus (as'in Figure 6-) may be mounted by pivot means 12 on afisuitable 40 swivel arm or like (not shown) mounted on'a lorry; container or such like, or on a tripod brpedestal or other obvious portable mounting means the pivot means 12 being so located' as to" give a balance of the apparatus to enable an easy 45 lift or the drum end by the handle means: 14.

In'operation describing first of all the apparatus ofFigures 1 to 5, with the engine 1 or like in motion the shaft 2 6 of flanged pulley l9'will be rotated by its drive pulley' 2 5 and the belt. 24:

will rotate the rotor 8 in the direction'as indi-' cated by the'arrow in Figure 3.

Thus the rotor boss l3 will rotate and pulley 15 .will cause pulley 58 to also rotate so that the crankpin 5'! of the latter will cause reciprocating motion of the arm 551(Figure 5) and also shaker shaft 44. j

7 These reciprocating motions of shaker shaft. 44 will cause its downwardarms 43 to move the screen 4| and its attached parts outwardly while the upward arms 53 cause the feeder 52 to move inwardly and vice versa.

Thus the spoil or the like put on screen 4| will be sieved and fall t the feeder 52 whichwill er -3 liver it to'the rotor' 8;istones or pieces of substance of excessive size .whichm'a'y be. too larg'efor' thep rotor' being prevented from passing through by the screen 4|. K Fl The spoil on falling from; the feeder 'meets the '7 travelling belt 24 and encounters the rotorblades 11 and asrthe optimum peripheral speed 'of the thrown from between the discs [0 and"! l; wh'erie 75 the belt 24 passes from same, with sufficient force to cause it to fly through chute 9 to the top section 29 which would be adjusted by the lever 36 to deflect said spoil to a downward course where desired.

Due to the chute 9 conforming to the natural trajectory of the flying spoil, the latter should pass therethrough without excessive rebound and for the purpose of obtaining minimum rebound the chute angle may be varied by the adjustment means 3! on the stays 39.

If any material should fail to pass up the chute 9, it will fall back along bottom 34 and through return opening 32 to the run back chute 59 which returns it to the screen 4! for further sieving.

Obviously the screen 4! and feeder 52 are not essential to the operation of the rotor 8 and chute 9 in that spoil could be shovelled direct to the rotor 8 through its admission hole IS.

The operation of the loader of Figures 6 to 11 is substantially the same as that described for Figures 1 to 5 with the elimination of the screen and feeder, the engine 7 driving the rotor 8 in the direction of the arrow of Figure 7 at an optimum speed (about 300 R. P. M. in the case of a two foot diameter rotor) the spoil or other substances being fed into the drum 59 by way of the admission hole lBa. in retaining ring 63.

The spoil in falling towards the bottom of the drum 59 encounters the blades I! which carry and throw the spoil through the gap with sufficient force to cause it to fly through the chute 9 to the top discharge end thereof where the tongue 69 is encountered which deflects the spoil to a desired downward course by manipulation of the lever means 10.

Due to the chute 9 conforming to the natural trajectory of the flying spoil, the latter should pass therethrough without excessive rebound from either bottom 34 or top 39 and by moving the chute 9 peripherally around the drum 59 as allowed for by the slotted holes 68 the best position for most effective operation can be obtained.

It will be obvious that the loader as shown in Figure 6 could be mounted in a frame I as in Figure 1, the drum 59 being rigidly secured to the frame I. Therefore with such modification, the screen 4| and feeder 52 could be applied to the apparatus, using the drum 59 in place of the belt 24 as the means for retaining the material within the rotor for a desired portion of the rotation thereof. (Alternatively a screen and feed mechanism could be attached to retaining ring 63 directly in front of opening I 6A).

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that what I claim is:--
